GAS-ENGINE.

SPECIFICATION forming part Of Letters Patent No. 607,276, dated July 12, 1898. Application filed January 25, 1895. Renewed December 21, 1897. Serial No. 662,935. (No model.)

To all whom it may concern: I

Be it known that I, JOSEPH REID, a citizen of the United States, and a residentrof Oil City, in the county of Venango and State of Pennsylvania, have invented certain new and usefullinprovcm entsin Gas-Engines,of which the following is a specification.

My invention has for its object to greatly simplifythe construction of gas-engines which employ gas as a fuel and to increase the efficiency of and economy in running such e11- gines.

My improvement consists in" certain novel features of construction to be hereinafter particularly pointed out and claimed and which will be fully understood upon reference to the accompanying drawings, in which Figure 1 is a plan View or" my improved gas-engine, partlyin section. Fig. 2 is avertical longitudinal section of the same across the web connecting the pump and'power cylinders on a much larger scale. Fig. 3 is a vertical transverse section extending through the web and valves of the air and gas ports. Fig. 4c is a detail axial section of the governor. Fig. 5 is a detail vertical section of the igniting-tube. Fig. 6 is a perspective view of the engine.

A is the bed, projecting across one end of which is a power-cylinder 1, having the usual water-jacket 1 which incloses the cylinder. Extending laterally from the power-cylinder 1 is a web 3, which supports a fuel pump-cylinder 2. To avoid any leakage, I cast the cylinders and their connecting-web in one piece.

The web 3 connects the rear ends of the cylinders, as shown, and is formed with a single connecting passage 11. By forming these several parts in one piece a great advantage is gained, inasmuch as no joints are present which would be liable to become broken, as is generally the case in engines of this class which have the water jackets bolted to the power-cylinder. This breaking of the joints in the engines ordinarily used is due to the unequal expansion and contraction of the power-cylinder and watenjacket caused by the excessive heat in the power-cylinder and consequent cooling after the engineis stopped from day to day. Thus it will be seen that by so forming these parts a great objection the check-valve.

.by means of the detachable cap 16.

is overcome and a consequent advantage is gained by users of this class of engines.

- Located within the power-cylinder 1 is a power-piston 1, which is connected with and drives the crank-shaft at through means of a pitman 5. The shaft 4 is mounted in bearings (5, located on the bed, and carries the balance-wheel 7. Through the medium of a crank-pin 8, located on the wheel, and'a pitman '0 the wheel operates the piston 2 of the fuel pump-cylinder 2. The pump-cylinder 2 communicates directly with the powencylinder 1 through a passage 11, cast in the connecting-web 3. Located in the uptake portion 11 of the passage isapuppet check-valve 12, seating downwardly, so that while yielding to pressure from the piston of the pumpcylinder 2 it confines the charge introduced to the power-cylinder 1 when the compression takes place and at the time of the explosion. To insure prompt closing of the check-valve 12, it is provided with a stem 13, which slides in an upper elongated hearing or sleeve 12, while its lower end is provided with a disk 14;, and between the bearing 01' sleeve and the disk is confined a spring 11' for seating For convenience in locatin g the check-valve and keeping it in repair I provide a removable hollow mounting 15, which is inserted transversely in a vertical channel '11 in the web, leads into the uptake 11, is held in place by bolts 15, and is closed By this means the passage 11 is cut off except through the bore of the mounting 15, with which it communicates through a port 11 and by which means the flow of fuel is brought under control of the check-valve 12, which seats on top of the mountin As this mounting is provided with the seat for the check-valve, I am enabled to replace at will one of the few wearing parts of the mechanism, and thus materially add to the life of the machine.

The fuel employed in this my improved gas-engine is preferably a mixture of gas and atmospheric air, and it enters the passage 11 through a vertical channel 17, also formed in the web 3, being drawn by means of the outstroke of the piston of the pump-cylinder past a puppet check-valve 1S, seating downwardly, which is mounted similarly to the check-valve 12 in a removable mounting 15 The capac= ity of the pump is such that on its outstroke it draws in a proper amount of gaseous fuel for a charge required by the engine and forces the same into the power-cylinder by its instroke. To supply the proper amount of gas mingled with air to the pump-cylinder to support proper combustion, I arrange a gas-inlet and an air-inlet 21 in the casting 15 and control them by sliding cylindrical valves 22 and 23, respectively. The cylindrical valves 22 and 23 are mounted to slide in cylindrical housings formed in the casting 15 and having each a closed end for the reception of its governor-rod 24 or 25 and perforated, as at 26, so that when the governor-rods are moved in a manner to be hereinafter referred to said perforations 26 are brought into greater or less coincidence with annular recesses 2'7, the admission of gas and air is regulated, and the charge which enters the power-cylinder to be exploded, and consequently the speed of the engine, are determined. The fuel-inlets, the seat for the check-valve 18, and the housings for the cylindrical valves. 22 and 23 are all formed in the casting 15 in which also are secured pipe or other means for conducting the fuel to the interior of the cylindrical valves 22 and 23.

The adjustment of either the air-valve or the gas-valve, or both, is made or varied by means of adjusting-nuts 25 on each governorrod. This is very important in an engine of this class, where, as is frequently the case at oil-wells, the pressure of the gas varies as the pumping proceeds, the variation often.

being so much that no ordinary range of governing would meet the case and as much as from one-fourth to one-half change in length of valve-rod is needed to enable the engine to continue running.

Any form ofgover11or,whether ball or wheel governor, may be used as the actuating device to move the governor-valves 22 and 2-3 in their work of controlling the admission of a larger or smaller charge of air and gas as condition of work the engine is doing requires. As this forms no part of my present invention it is not necessary that it should be described. In order to ignite the charge of fuel in the power-cylinder, I attach an ignitingtube to the rearend thereof and keep this tube constantly heated by means of an adjacent burner 36. When the gas has been compressed by the return of the power-piston, it will be forced into the igniting-tube 35 by the act of compression, and the ignition will follow. It will thus be seen that the ignition takes place when the power-piston has reached the point of greatest vantage.

37 represents the exhaust-ports, which are uncovered by the piston upon reachingits outermost limit and which communicate with a chamber 38, leading to an exhaust-outlet 30.

From the foregoing description it will be seen that I have provided an engine wherein the two cylinders, with the connecting-web and water-jacket, as well as the connectingpassage between the cylinder, are formed of an integral casting without joints and the great difficulty which is generally experienced in machines of this class is avoidednamely, leakage of joints.

Having thus, described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

1. A gas-engine comprising a power-cylinder, a pump-cylinder, a connecting-web for the cylinders having a passage extending therethrough, a Vertical power-valve channel and a vertical pump-valve channel, the removable mounting having a puppet check valve and inserted in the power-valve channel,and the removable mounting formed with two cylindrical valve-housings in its lower portion provided with a puppet check-valve, and two cylindrical valves,and inserted in the pump-valve channel; substantially as described.

2. A gasengine comprising a removable pumpvalve mounting formed with cylindrical valve-housings, annular passages surrounding the housings and gas and air inlets connecting with the passages, the puppet check-valve and the cylindrical valves having perforations and adjustable as to length of play in the housings; substantially as described.
